An analougy would be: I can drive slow in a slow and a fast car, but I can only drive fast in a fast car.
So the stepper with the higher current rating will behave almost equally at low current and I can raise the current, if I see skipped steps later...
Holding torque isn't the most important figure in the list, but resistance and inductivity. They determine how fast the stepper can run at 12V and how hot it will get.
Lower inductivity can run faster. Lower resistance stays cooler ( at the same regulated current )
